cylinder moulds and vats and in the preferred The end Wall members 24 are provided with form thereof it will be describedin connection outlets of some sort indicated generally by 48. with the accompanying drawing wherein: The end plates 26 as shown in Fig.' 2 are provided Fig. 1 is aside elevational view of apaper-makwith outwardly extending walls such as 50, 52, 55

posed outer walls 64 to form one or more compartments which are located at opposite ends of and separate from the vat.. A vertically eX- tending wall 66 is provided so as to form in conjunction with the vertical wall 62 an overiiow compartment which is sepa-rate from another compartment formed by walls 50, 52, 54r 56, 58, and 66 which compartment is in communication with the vat through openings 48.

As has been described, the paper-making material, which is usually fibrous material suspended in water, is delivered to the vat through the pipe 46 so that it flows upwardly and over the member 30 into the space between thecylinder mould and members 34 and 40. In ordinary practice, water flows through the mould in such a way that the bers are deposited thereon and the water then flows outwardly through the ends ov the cylinder mould, through openings 48 into the chambers formed on the end plates. The chambers on opposite-ends of the vat are connected by a pipe '70 which'in turn is connected as shown to al discharge pipe such as '72. Thus water which passes through the cylinder mould or the depositing of fibers is conducted away from the vat by means of the pipes 70 and 72.

The endsv of the cylinder mould are sealed against the ends of the vat in any suitable way such as byA a more Aor less flexible strip 9 associated with a seal ring 1l carried by the end walls, the strip overlying a circumferential ange associated with the ends of the cylinder mould, as shown.

'The chambers between the walls 62 and 66 are' overflow chambers and the walls 66 are prefer-- ably of such a height or may have some means associated therewith sothat a desired height ofv material is' maintained in the vat. When the material overflows into the 'overflow chambers it may be conducted away therefrom by means of pipes 76. Y

In lieu of the vat described, of course, it may be esirable in some cases to use a vat constructed dinerently, the form shown being merely Vfor purposes of assisting in the description and disclosure of the invention.

As one novel feature oi the invention it is desired to agitate, vor create such movements in the paper-makingmaterial as will bring about an intermingling and feltingl o1" the fibers thereof. To that end means is provided to facilitate vibrating the vat and cylinder relative to one another and such means will now be described.

The cylinder mould has a shaft which is iournalled in bearing standards 82 at the front and rear sides oi the vat while stuffing boxes such as 84 are associated with the shaft and the end wall of the vat to permit relative axial movements of the cylinder and vat.

Socket members 86 are provided on the under side of the vat and similar members 88 are pro- 54, 56, 58, 60 and 62 connected to vertically disvided whichmay be associated with a plate 90. The sockets 88 and/or the plate 90 associated therewith may be supported by a floor or foundation. The adjacent faces of the members 86 and 88 are provided with curved sockets as shown so that rollers 90' may be disposed therebetween and in that way the vat is so mounted that it may be moved back and `forth or vibrated. Any means other than this, such as links connecting the vat to a suitable support, may be employed, it being essential that some means be provided to permit slight relative endwise movements of the vat and of the cylinder.

Various means may be employed to bring about vibration of the vat but, for purposes of description, a vibrator indicated generally by V is shown.

This vibrator V may consist of a disc 94 havingr a shaft rotatable in a standard 96 and the shaft may have a pulley 98 associated therewith which is driven from any suitable source of power. The disc is slotted on its outer face as at 100 and a block. such as 102 is adjustable transversely to the axis of rotation of the disc by means of bolts 104 engageable with suitable nuts working in the slot 100. A stud 106 is provided on the block 94 and it is connected by means of a connecting rod 108 to a bracket such as 110 provided `on the end of the vat. By moving the block 10,2 the position ci stud 106 may be varied relative tothe axis of rotation of member 94.

Thus as the disc rotates the vat is vibrated i slightly to more or less agitate the paper-making material therein and cause the fibers thereof to be thoroughly intermingled so that when they are taken on by the cylinder mould they are disposed at various angles to one another. ln that way it-is possible to produce a layer ior a web of paper which is' strong and durable and by employing a plurality of vats and agitating them as described the layers for the web may be properly superimposed with each layer having the i'lbers thereof well felted or inter-mingled so that the combined layers form a very novel and superior web of paper. l

While I have described my invention in great detail and with respect to preferred embodiments thereof, I do not desire to be limited yto such detail or embodiments since many changes or modifications may be made without departing from the spirit and scope oi the invention in its broader aspects. What I desire to claim as new and secure by Letters Patent' of the United States is:

The combination in a cylinder paper-making machineof, a support, a vat mounted on said support for movements relative thereto,fsaid vat having side and bottom walls rigidly secured together, bearings rigidly associated with said support, a cylinder mould in lsaid vat having end parts `journalled in said bearings, means associated with said vat for bringing about said movements thereof relative to said support.
